Infinity

`Infinity`

is a property of the *global object*, i.e. it is a variable in global scope.

The initial value of `Infinity`

is `Number.POSITIVE_INFINITY`

. The value `Infinity`

(positive infinity) is greater than any other number. This value behaves mathematically like infinity; for example, any positive number multiplied by `Infinity`

is `Infinity`

, and anything divided by `Infinity`

is 0.

Per the ECMAScript 5 specification, `Infinity`

is read only (implemented in JavaScript 1.8.5 / Firefox 4).

console.log(Infinity ); /* Infinity */ console.log(Infinity + 1 ); /* Infinity */ console.log(Math.pow(10, 1000)); /* Infinity */ console.log(Math.log(0) ); /* -Infinity */ console.log(1 / Infinity ); /* 0 */
